Alright. Let's see a show of hands. Who wants woolen underwear? It's health underwear (as opposed to sickness underwear, I guess).
Hey, the Royal Flying Corps or England wear it. Exactly why any Yanks would care what underwear English fliers wear escapes me. (I found this ad in the December 1918 issue of Cosmopolitan, which is an entirely American magazine). But heck, if it is scratchy enough for those English boys, err, I mean soft enough for their private parts...
I hope you get as good a laugh out of this ad as I did.
